Distilled water is extra. It’s water that went to spa school.
First, you boil the water until it turns into steam. Then you catch that steam and condense it back into liquid.
Everything else—minerals, bacteria, weird tap chemicals—gets left behind.
What’s left? H₂O. Nothing else. Pure, naked water.
Quirky detail: Distilled water is so “empty” that it steals minerals from your mug if you let it sit too long.
It’s a thirsty little ghost.
